326 THE MICROSCOPIST. 



filamentous mycelium, which becomes septate with age. 

 The spores are set free by breaking of the wall of the 

 sporangium. 



C. CLEFT FUNGI, SCHIZOMYCETES (bacterium, micrococcus). 



The term schizomycetes is given from the great fra- 

 gility of the formation. They are cells without chloro- 

 phyll, of various forms, which increase exclusively by 

 transverse division. The cell-membrane is not destroyed 

 by potassa, nor by acids, and resists decomposition for a 

 lono; time. 



O 



1st Group. Spherobacteria. Globular bacteria (Pas- 

 teur's Monas or Mycoderma. Ehrenberg's Monas corpus- 

 culum and prodigiosa. Hallier's Micrococcus}. 



Spherical or oval cells, without granular contents, pos- 

 sessing a double contour, and becoming moniliform by 

 division. Often difficult to distinguish from granular 

 detritus. 



1st Genus. Micrococcus (Cohn). Bells colorless or nearly 

 so, very small, united into short moniliform filaments of 

 two or more members (mycrothrix, torida-forms], or into 

 many-celled families, balls, or colonies, or into mucous 

 masses (zoogloa-forms, m.ycoderma-forms). No movement. 



(1.) Pigment bacteria. Appearing in colored jellylike 

 masses. 



a. Coloring matter, insoluble, red and yellow. 



1. Micrococcus Prodigiosus (Palmdla prod.). Cause of 

 the seeming blood-spots which sometimes appear during 

 moisture on wafers, bread, potatoes, etc. 



2. M. luteus. 



b. Coloring matter, soluble. M. aurantiaceus, chlorinus, 

 etc. 



(2.) Zymogenic globular bacteria. 



3. Microccocus Urea. Ferment of urine.
